LAMP-BURNER.

Specification of. Letters Patent. Patenttl Se'pt. 12, 1911 Application filed October 20, 1910. Serial No. 588,019.

To all whom it may concern.

Be it known that I, FURMAN D. SPEAR, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Lamp-Burners, of which the following is a specification.

This invention relates to that class of lamp burners which are known as long time burners and which are used extensively in signal lampsand switch lamps. Burners of this kind are used with or without chimneys,depe'nding upon local conditions, and the object of this invention is to so construct the burner that it can be readily supplied 'With a chimney holder or be used without the same, as ma be desired.

In the accompanyin drawings: Figure 1 is a side-elevation an partial vertical section of a burner embodying this invention, when used as a chimney burner. Fig. 2 is aside elevation of the burner without the chimney holder. Fig. 8- is a detached plan view of the chimney holder.

Like reference characters refer to like parts in the several figures.

1 represents the body of the burner provided at its base with suitable means for .collar 11, which forms the attaching base of the flame spreader, is screwed into the supporting collar 5 and extends with its flange over the lugs or tongues 6 of the same.

7 represents the chimney holder or sup port having in its body or plate an opening 8 by which it fits around the base collar 11 of the lame spreader. The holder is providcd in said opening with notches 9 in which the lugs or tongues of the collar 5 engage and .whereby the holder is ,held against turning on the supporting collar The holder is provided with upwardly-exc tending curved arms between which the lower portion of the chimney is held, as indicated by dotted lines in Fig. 1, and it is desirable to secure the holder in such a position that these arms cast no shadows upon the lenses of the lamp. The interlocking lugs and notches of the supporting collar and holder are so arranged as to hold the in position, as represented in F ig. 1. If it V is desired to use the burner without a chimney holder, the flame spreader is unscrewed,

the holder removed, and the spreader returned toits normal position, in which condition the burner is represented in Fig. 2.

. I claim as my invention:

1. A lamp burner comprising a body provided at its lower end with means for one gagement with an oil pot and in its upper portion with a support for a chimney holder, a removable chimney holder resting on. said support, and a removable flame spreader PIOVld-Bd with an attaching base adapted to be secured to said body and to hold the chimney holder in place on its support,'substant1ally as set forth.

2. A lamp burner com rising a body having an upwardly-extending su'port for a chimney holder, a removal) e chimney holder resting on said support, means for preventing rotary movement of the holder on its support, and a flame spreader provided with an attaching base by which it is secured to the body of the burner and which holds said holder on its support, substantially as set forth.
